If you are going to get new shafts in 2117, you may already know of eastons Game getters. The 400 size is the same as 2117. My boys both shoot that same shaft, and they are proving to be much tougher then the old style easton game getters, and have surpassed my expectations. They dont break the bank either, which makes it nice. Even the Game getters will be more consistent then wood by far, and anymore I love and shoot wood exclusively and successfully. I dont think there is a spits worth of difference in the XX75 line as far as material. (Camo hunters,legacy)
